Vince M. asks, "I'm surprised you haven't written about Radient Pharmaceuticals ( RPC) since its big move in December. What are your thoughts about Radient's cancer test? The stock has fallen back and looks more attractive at these levels, especially if the company can make millions of dollars from India." I'm late to the Radient story not for lack of interest but because I've been waiting almost a month to schedule an interview with Radient CEO Doug MacLellan to discuss the company's Onko-Sure cancer screen. MacLellan canceled one interview with me. I tried to reschedule several times through Radient's media person with no luck, so I'll move ahead. Radient is investing a lot of money into investor and media relations, which helps explain the mini stock-price bubble. Press releases are flying out the company's door filled with announcements about international distribution deals for the Onko-Sure cancer test. At the same time, MacLellan is granting interviews with a biotech stock promotions Web site claiming Onko-Sure is on the cusp of generating millions of dollars in revenue. A fine line exists between optimism and delusion, and I'm afraid MacLellan might be on the wrong side of the divide. Past performance isn't necessarily an indicator of future results, but in Radient's case, it's a damn good proxy. Onko-Sure sales for the first nine months of 2010 totaled $116,000, a 15% decrease from sales in the first nine months of 2009. Radient's loss from operations through the end of September 2010 was $6.7 million; add in losses from discontinued operations and business units Radient is trying to sell, and the total net loss was $38.4 million.
